Hunting on NSW public land will be banned for at least the next two months and the Game Council will be disbanded after a review into the council.

But the State Government will go ahead with its plan to allow volunteer hunters in national parts as part of a pest control program.

A highly critical report into the governance of the Game Council found its position as regulator, promoter and operator of hunting activities in NSW was inherently conflicted, says Primary Industries Minister Katrina Hodgkinson.

The review was ordered after the council's acting chief executive, Greg McFarland, and a volunteer were charged with illegal hunting and trespass.

The council's functions will be transferred to the Department of Primary Industries and hunting in 400 state forests and two crown lands will cease until a new advisory board can be established.

The changes will help manage the "costly and environmentally destructive" issue of pest animals, Ms Hodgkinson said.

"The overall direct economic impact of the pest animals has been conservatively estimated at $740 million annually," Ms Hodgkinson said.
